Copied a friends non purchased itunes library

Hi, I copied a non purchased music library from my friends iTunes library to my iPhone 4, now i would like to add all that music to my iTunes library on my PC. Can anyone please tell me step by step how to do that, without downloading another program? I dont think she synced my iphone with her pc (if that helps). Also, once i get the songs on my pc will i be able to sync my iphone normally? Thank You

If you copied it from their library to your phone you did sync with her machine. If you sync with yours you will delete everything off. Sorry, but there is no way I know of to do what you are attempting.

Either of these programs will do the trick, I bought TouchCopy 2 years ago for this purpose:
